AERIAL TOY.

, Specification of Letters Patent.

Patented Jan. 21, 1919.

Application filed January 10, 1918. Serial No. 211,127.

To all whom it may concern.-

Be it known that I, HYOK-IC-HI Manor, 9.

subject of the Emperor of Japan, and resi-,

dent of the borough of Manhattan, city, county, and State of New York,have invented certain new and useful Improvements in Aerial Toys, ofwhich the follow-,

ing is a specification.

This device is a development or addition to the ordinary toy balloon,and has for its princlpal object the provision of a means which willcause the balloon to travel upward at a high rate of speed when the airis allowed to discharge therethrough.

he provision of a rapidly revolving propeller not only makes theaccomplishment of the object possible, but also adds materially to theattractivene s of the device or toy.

The following is what I consider a good means of carrying out myinvention, and the accompanying drawings should be referred to for acomplete understanding of the specification which follows.

In the drawings:-

Figure 1 is an elevation of a complete device in condition foroperation.

Fig. 2 is a sectional and Fig. 3 a plan of the propeller.

Similar reference numerals indicate like parts in all of the figureswhere the ap ear.

The balloon 1 shown in Fig. 1 may of any desired shape or size, and maybe constructed similar to the well-known toy balloon, which is formed ofindia rubber, at one end of which is provided a nipple or air-inlet 2.

In the nipple 2, I place an air-nozzle 3,

which may be formed of wood, or metal,-

and it will be noted that unlike ordinary toy balloons, I do not providea valve or check adjacent or upon the air-nozzle.

The air-nozzle 3 is provided with a longitudinal and tapered passage 4extending therethrough, and a circumferential groove 5, Whichthe nippleof the balloon will engage.

Secured in the circumferential groove 5, is a flexible member 6 whichmay be a thread or a wire member knotted or secured in the groove 5, andextendi downward from the nozzle 3 to a desirab e, though somewhatlimited extent.

Upon the end of the flexible member 6, I place a rotatable device orpropeller 7 shown in plan in Fig. 3.

the blades. It will view of the air-nozzle,

' invention, what I The member 7 should be provided with a plurality ofblades extending around a common axial center, and the blades are soconstructed that no sharp angles are present in be noted that 8, 9, and10 of the propeller are of peculiar shape, andare not ordinary propellerblades. I have found by experiment that blades having an enlargedportion with a reduced extension within the line of the periphery of themain portion of the blade will produce a propeller that will revolverapidly from the pressure of the air escaping through the nozzle 3.

The operation of my device may probably be understood from thedescription and its construction. -However, I will briefly refer to theoperation so that the full value of my invention .may be appreciated.

When the balloon is deflated, it will have the Same general appearanceof an ordinary balloon of its shape and size. The bag portion 1 will beloose and flexible.

tion shown in Fig. 1, and then, with the finger, placed over the openingof the nozzle 3, the balloon is removed from the lips, and when thepropeller 7 extending downward away from the balloon, the fingers arereleased, and the balloon is allowed to drift away. The pressure of theair escaping from the nozzle 3 and impinging upon the propeller 7 willrapidly revolve the propeller urging the balloon upward, andwhile I havefound that a balloon of this type and with a free air passage throughthe nozzle 3 will not elevate to any appreciable extent when released,the addition of the propeller will cause a similar balloon to soarupward to an extraordinary height. An advantage of the device as a toyresides not only in the entire construction and its ability to performin a. manner uncommon in ordinary ballons, but the revolving propellerwill also prove attractive because of its novelty and its control overthe action of the balloon.

I believe that modifications may be made within the scope of theappended claims, but I prefer the whole as shown and described.

Having carefully and fully described my claim and desire to secure byLetters Patent is:

1. A toy balloon having a nozzle provided with an unobstructed andtapered air passage therethrough, and a propeller in axial alinementwith said air passage but spaced therefrom and a flexible membersecuring said propeller to said nozzle.

2. An air balloon having an air passage, a nozzle provided with atapered discharge passage and arranged in said air passage, a flexiblemem'ber secured to said nozzle, and a propeller having a plurality ofapproxi- 1o mately flat blades and rotatably secured to said flexiblemember, said propeller being arranged with its axis approximately inline With the axis of said nozzle, and Within the line of air dischargefrom said nozzle;
